According to the teachings in Chapter 21 of Sai Satcharitra, what is the underlying relationship between different Saints and Sages?

Chapter 21 explains the profound and mystical connection between all Saints and Sages. It states that although they may take incarnations in different places and at different times for specific purposes, they are "essentially inseparable from one another." The text emphasizes that while their external circumstances like country and time may differ, they are inwardly all one. As Chapter 21 puts it, "the signs of one are known completely by another Saint." This teaching reveals a secret arrangement and a unified spiritual consciousness among these great souls, suggesting they are all manifestations of the same divine principle, working in unison for the spiritual upliftment of humanity.
